TXS0102DQER Voltage Level Translator Bidirectional 1 Circuit 2 Channel 24Mbps
The TXS0102DQER is a dual-bit, auto-direction-sensing voltage-level translator from Texas Instruments, designed to seamlessly bridge bidirectional data lines between different voltage domains without the need for a direction control pin. It operates with two fully configurable power supply rails: Port A supports a voltage range from 1.65V to 3.6V, and Port B supports a wider range from 2.3V to 5.5V, enabling robust translation between modern low-voltage processors and higher-voltage peripherals. The device employs a unique circuit topology that integrates edge-rate accelerators and one-shot circuitry, allowing it to translate between slow, open-drain outputs (like I2C) and fast, push-pull CMOS signals with minimal propagation delay and excellent signal integrity.
This translator features two independent bidirectional channels, supporting data rates up to 24 Mbps for push-pull applications and critical timing for I2C speeds up to 2 Mbps. The integrated edge-rate accelerators on the B-side output drivers actively improve rise times for capacitive loads, ensuring reliable communication. Key electrical specifications include 3.5 ns (typical) propagation delay and robust ±8 kV HBM ESD protection on the I/O pins, enhancing system reliability. It requires no external pull-up or direction control components for basic operation, simplifying PCB layout and reducing the overall bill of materials.
TXS0102DQER I2C voltage level shifter Applications
